• Develop, maintain, and optimise automated UI and API test suites using Selenium, Postman, JMeter, and gRPC.
• Integrate automated test execution into CI/CD pipelines and actively monitor stability and performance.
• Design and execute complex manual test scenarios where automation is not feasible – ad‑hoc, usability, and integration testing.
• Collaborate with cross‑functional teams to ensure test environments are stable, scalable, and production‑representative.
• Document, manage, and triage defects using Azure DevOps, ensuring clarity and timely resolution.
• Act as a quality owner for key product features, ensuring traceability from requirements to release.
• Build and maintain a scalable, reusable automation test library and produce meaningful test coverage reports.
• Mentor junior QA engineers in both manual and automated test design, process, and tooling.
• Identify opportunities for process improvement and propose tools or scripts to enhance QA efficiency and accuracy.

• Minimum 3 years of experience in software QA, including 1–2 years in a senior or lead role.
• Strong understanding of Agile/Scrum methodologies and CI/CD practices.
• Advanced English (written and verbal) for global team collaboration.
• Strong analytical and problem‑solving skills.
• Demonstrated experience mentoring QA engineers and improving QA processes.
• Willingness to travel up to 10% as required.

Preferred Qualifications

• Experience testing microservices, distributed systems, or cloud‑native applications.
• Familiarity with BDD/TDD practices.
• Proficiency with TestNG, JUnit, or Cucumber.
• Background in performance, load, security, or contract testing.
• Familiarity with version control tools (e.g., Git) and infrastructure‑as‑code practices.
